Hello, Dilges Yildiz,
Thank you for purchasing our theme.
The site you provided only shows a blank screen, please check.
To install the theme follow this article – https://xstore.helpscoutdocs.com/article/12-theme-installation
If you already have content on your site, you don’t have to import the demo content.
If your site is live, you can create a staging site (activate the theme using the same purchase code), and do a test there first.
If you have any additional questions or concerns, please do not hesitate to reach out to us. Our support team is always available to assist you.
Kind Regards, 8theme team
